Abstract Changes in the velocity and attenuation coefficient of quasi-longitudinal waves propagating in TGSe crystal in the direction X induced by uniaxial stress σY were measured in the temperature range of ferroelectric phase transition. The application of uniaxial stress was found to shift the phase transition temperature by ∂TC/∂σY = −0.18 K/MPa. For the stress greater than 2 MPa an additional anomaly in the wave velocity and attenuation appears, which has been interpreted as a splitting of the phase transition.
